SPRING WHEEL.

Application filed January 8, 1923.

Y '0 all whom it may concern:

Be it known that I, THORVALD H. MATHE- SON, a citizen of Norway, residing at Casper, in the county of Natrona and State or Wyoming, have invented new and useful Improvements in Spring Wheels, of which the following is a specification.

The object of this invention is to produce a vehicle wheel of a construction by which shocks and jars to which the wheel is subjected will be effectively absorbed.

A further object is to produce a vehicle wheel having telescopically related spring influenced spoke sections associated and connected in a manner whereby shocks and jar delivered on the tread of the wheel will be absorbed by the spokes thereof.

To the attainment of the foregoing and other objects which will present themselves as the nature of the invention i better understood, reference is to be had tothe drawings which accompany and which form part of this application.

In the drawings-:- a

2 Figure 1 is a side elevation of a vehicle wheel in accordance with this invention.

Figure 2 is a greatly enlarged sectional View on the line 22 of Figure 1.

Figure 3 is a sectional view on the line of Figure 1, also on an enlarged scale.

Figure 1 is a similar sectional view on the line 4-4 of Figure 1.

Figure 5 is an end view of the member 19 shown in Fig. 2.

The hub of my improved vehicle wheel includes two spaced disks 1 having central openings that receive therethrough and have secured therein the boxing in which the axle spindle is journaled. The disks, adjacent to their outer peripheries are provided with circumferentially arranged equi-distantly spaced openings that align, and through these openings there are passed bolts 2 engaged by the usual nuts. Each bolt 2 passes through a bearing opening in the widened inner end 3 of the inner sections of the spokes of the improvement. Each of said sections, indicated by the numeral 4, includes a spindle-like body 5 having a reduced extension 6 at its outer end, the ends of the said extension being preferably threaded. For distinction, the shoulder provided between each spindle 5 and its extension 6 is indicated, in the drawings, by

the numeral 7.

Serial No. 611,361.

The outer spoke sections each comprise a tubular member 8 having, adjacent its outer end, a reduced extension or neck 9, the latter being widened at its outer end, as at 10 and provided with a transverse openso ing 11.

The tire 12 for the wheel may be solid, and is received in a rim 13 having its inner face provided with depending lugs 14, and passing through these aligning lugs and through the opening 11 in each of the outer spoke sections, is a bolt 15, engaged by a suitable nut.

F or distinction, the shoulder between the tubular spoke section 8 and its neck portion 9 is indicated, in the drawings, by the numeral 16. The inner end of each of the members 8 is threaded, and there is arranged around the spindle extension of the inner spoke section 8 a cap nut 17 which is screwed on the said threaded end of the spoke section 8. Each cap nut 17 has on its outer face a pocket for a. packing, and closing each pocket there is a packing nut 18.

Loosely arranged on the extension 6 of each oi the inner spoke sections a there is a tubular member 19 having its inner end flanged inwardly, as at 20 and its outer end flanged outwardly, as at 21. In the bore of the tubular member 19, surrounding the extension 6 of the inner spoke members 4; and secured to said extension there is a. collar 22.

Surrounding the spindle portion 5 of each spoke section a, and received in the outer section 8 thereof, there is a tubular member 23 of'a similar construction to the tubular member 19. Th tubular members 23 have their outer ends flanged inwardly, as at 24, the extension 6 of the said spoke sections passing through central openings in said 5 flanges. Each tubular member has its inner end firnged outwardly, as at 25, and surrounding the tubular members 19 and 23, and having its end convolution resting on the flanges 21 and 25 thereof, there is a helical spring 26 whose convolutions are comparas tively wide.

When the spoke sections and the remainder oi the wheel are assembled as above set forth, the packing nuts 18 are removed and the interior 01" the hollow spoke sections are filled with cup grease, the nuts being replaced to prevent leakage of th lubricant between the cap nut 17 and the spindle 5 of the inner spoke sections 4. An inward pressure exerted on eny of the spokes Will cause the shoul ders 16-111 the'hollow or outerispokesections 8 to contact with the flanges 21 on the tubular members 19 to compress the springs 26. This compression of the springs Will cause the same to move the tubular members 23 until the flanges 24 thereof are brought to contacting engagement With the shoulders 7 on the spindles 5. This doesmot limit" the full invvard movement of the outer spoke sectiofi' '61'1 'Etheinnerspoke section, j as "the springs QGare' iiot'i ully compressed, but the l'etter're and absorb-every shock imparted "to the spoke.
